TNY264PN

POWER INTEGRATIONS · AC-DC Controllers and Regulators · DIP-8B

TNY264PN from POWER INTEGRATIONS, in a DIP-8B. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BP power_in BYPASS pin. Connection point for a 0.1 µF external bypass capacitor to the internally generated 5.8 V supply. Also served by an internal 6.3 V shunt regulator for optional external bias-winding powering.
2 S power_in SOURCE pin. Control-circuit common, internally connected to the output MOSFET source. Serves as signal-ground reference for BP and EN/UV.
3 S power_in SOURCE pin. Control-circuit common, internally connected to the output MOSFET source.
4 EN/UV input ENABLE/UNDERVOLTAGE pin. Dual-function enable input and line undervoltage sense. MOSFET switching is terminated when >240 µA is drawn from this pin. An external resistor from the DC bus programs the line undervoltage threshold (~49 µA to initiate switching, ~2 µA disables the UV function).
5 D power_in DRAIN pin. Power MOSFET drain connection (700 V rated). Also provides internal operating current for start-up and steady-state operation, eliminating the need for a bias winding.
7 S_HV_RTN power_in SOURCE (HV RTN) pin. Output MOSFET source connection for high-voltage return current. Connected to the primary-side bulk return.
8 S_HV_RTN power_in SOURCE (HV RTN) pin. Output MOSFET source connection for high-voltage return current.

CAD (KiCad official)

  • Symbol: TNY264PN
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: DIP-8B (KiCad packages3D, STEP)
  • 3D model files: tny264pn-etched.step / tny264pn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tny264pn.step / tny264pn.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tny264pn.step 271 KB You want the bare part, or you mark your own boards.
tny264pn-etched.step 1.5 MB You want the part with TNY264PN already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 382 faces against 148 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: POWER INTEGRATIONS datasheet (22 pp, sha256 97b14aa7b280edc7, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
